So basically, I'm trying to adapt this to UXP:
https://bugzilla.mozilla.org/show_bug.cgi?id=1281135
The earliest source of difficulty while adapting Bug 1281135 to our codebase was simply getting the new ErrorResult flag added to the SetDisabled function to play nice with the SetMozDisabled function. At this point, the implementation can actually have a stylesheet be disabled by default but there are supposedly issues with alternate stylesheets.
At first I played around with the return type of SetMozDisabled to no avail, but I found another solution fairly quickly.

Essentially, the way around the problem of the number of return arguments not matching up is to declare a local variable within SetMozDisabled called ErrorResult rv, and using that to store the return value of the ErrorResult argument from SetDisabled. After that, because ErrorCode was removed, you would return rv.StealNSResult() in order to report success or failure to any consumer that calls on SetMozDisabled.
Newly introduced aspect-ratio property did not have CSS_PROP_LIST_EXCLUDE_INTERNAL defines, resulting in the following assertion:
\!nsCSSProps::PropHasFlags(p, (1<<28)) (properties defined outside of #ifndef CSS_PROP_LIST_EXCLUDE_INTERNAL sections must not have the CSS_PROPERTY_INTERNAL flag), at ...layout/style/nsCSSProps.cpp:289
This patch resolves the assertion by adding #ifndef around the aspect-ratio property.
Since this is supported as an alias by Firefox and Edge for the same
reasons and we have websites using this to (attempt to) override the
system-provided styling with their own, leaving out the only supported
keyword we'd otherwise have (with -moz- prefix) but still stating
-webkit-.
TODO: unprefix this completely and make the vendor prefixes aliases.
This is apparently used for fallback selection and if available it is "assumed"
Shadow DOM is also available, while this is a utility function.
Webcompat is a nightmare sometimes.
At first, HTMLEditor::GetActiveEditingHost might return null in this situation, we should check whether nullptr is returned. At second, SplitNodeDeep returns error since curent is design mode and selection node has no parent. So we should check error.

Aspect Ratio handling simplified by using floating point integers:
- Multiplication of value (or inverse value) to a known side for Scaling
- No unequal equal values such as "4/3" vs "8/6" vs "20/15"
- Truly "Empty" aspect ratios, even if one dimension is not 0
I meant to do this a long time ago, but basically it accounts for the new XP_SOLARIS build flag that never made it into the MailNews code. Additionally, it enables a compatibility flag for Solaris 11.4 that allows us to use the three-argument implementation of ctime_r still used by Solaris 11.3 and illumos (which also appears equivalent to the NSLDAPI_CTIME implementation used by libldap internally). Also, the ctime_r function has been added to the time.h header library for a while now, not sure why Mozilla thought we didn't have a ctime_r implementation.
When using AF_CONN addresses, don't put these in the COOKIE
chunk. For these addresses it is possible to reconstruct them
locally. Conceptually, addresses are something to be shared
with the peer, but in the case of AF_CONN this might not be
the case. Therefore, zero then out.
Thanks to Natalie Silvanovich of Google Project Zero for
finding and reporting the issue.
JIT optimizations involving the Javascript 'arguments' object could
potentially confuse later optimizations, so we simply disable these
optimizations as a DiD measure.
These should all be spec-compliant and were (for release-trickling of features)
arbitrarily disabled by Mozilla at our fork point. There's no real reason to
keep them disabled since they are used in the wild.
A version bump triggering add-on compatibility check will re-evaluate the "native" status (among other things) so no extra or special work is required to fix erroneous warnings.
tl;dr instafix!
